Jennette McCurdy disliked Ariana Grande while filming Sam & Cat

In Jennette McCurdy’s new memoir, I’m Glad My Mom Died, the former Nickelodeon star is brutally honest about her feelings toward Ariana Grande, the music icon who briefly dated McCurdy on spinoff series iCarly and Victorious seeing was “Sam & Cat.” Grande’s pop star career began while filming the show, which only ran for a single season on Nickelodeon.

McCurdy writes that she grew increasingly annoyed with Grande as she “regularly” missed filming “to sing at award shows, record new songs, and press for her upcoming album” (via Entertainment Tonight). McCurdy, on the other hand, had to “angrily hold down the fortress”.

“The week I was told that Ariana would not be here at all and that they would rewrite her absence in this episode by locking her character in a box. are you I’m joking,” writes McCurdy. “So I have to turn down movies while Ariana whistles at the Billboard Music Awards? Crap. This.”

According to McCurdy, “She booked two feature films during iCarly,” which she “had to turn down because the iCarly crew didn’t want to write [her] no more episodes to film them.” Grande was allowed to skip episodes to work on her music career.

“That’s it. Ariana misses working on her music career while I play with a box,” McCurdy writes. “I’m mad about it. And I’m mad at her. Jealous of her.”

McCurdy continues, “Ariana is at a stage in her career where she’s on every 30 under 30 list in existence. And I’m at a point in my career where my team is thrilled that I’m the new face of Rebecca Bonbon, a tween clothing line with a cat with a tongue out. Available exclusively at Walmart. And I often make the mistake of comparing my career to Ariana’s. I can not help myself. I’m in the same environment as her all the time and she doesn’t exactly try to hide her achievements.”

What finally made McCurdy reject Grande outright was when Grande came to the set one day and revealed that she “spent the previous night playing charades at Tom Hanks’ house.”

“That’s when I broke,” McCurdy writes. “I couldn’t take it anymore. Music performances and magazine covers… whatever, I’ll get over it. But playing a family game at the home of two-time Oscar winner and six-time nominee Tom Hanks? I’m done.”

McCurdy adds that from that moment on, “I didn’t like her. I might not like her,” he added. “Pop star success I could handle, but hanging out with Sheriff Woody, Forrest fucking Gump? This has gone too far. Now every time she’s absent from work, it feels like a personal attack.”

I’m Glad My Mom Died is available now and has already topped the Amazon bestseller list. The memoir includes several shocking revelations from McCurdy’s years of work at Nickelodeon, including a claim that the studio offered her $300,000 in hush money to keep quiet about the alleged abuse she was dealing with behind the scenes.
